Good product and works well for my purposes. Read reviews and deal with them appropriately and as instructed. They are very strong, can be attracted to themselves and break easily. I am an experienced carpenter. They are not toys, not suitable for classroom demonstrations and inexperienced users, and have jagged edges if broken. I'm deducting a star as I think the seller should state this clearly in the description to avoid most of the negative feedback. The adhesive strips weren't strong enough for my purpose, check first if they might work for your purpose.
